I run inside and out during from late fall to early spring. I also have a home spin bike. I have practiced yoga for about 6 years and do resistance and core work with a trainer twice each week. I love to ride, but I tend to think that it needs to be balanced out with other activities. There are a number of muscle groups that get underworked or not worked at all on the bike. Plus, it's not weight bearing. Cycling just doesn't check all the necessary boxes for me, nor does just cardio.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
